GOLDMAN GARMENT STEAMING AND PRESSING MACHINE Original Filed Jan. 8, 1929 INVENTOR ATTORN EYS Patented June 27, 1933 UNITED STATES Y WILLIAM GOLDMAN, OF BROOKLYN, NEW YORK .GARMENT STEAMING AND` PRESSING MACHINE Application filed.v January S, 1929, Serial No. 331,103. Renewed November 18, 1932.

videa lower or stationary buck of garment steaming and pressing machines with improved steam supplying and exhausting means in order that the amount of steam vused in the steaming and pressing operations may be reduced to a minimum.

f Another object of the invention is to providey means to admit steam to the steaming chamber and to the garment from the upper f part of the heating chamber where the steam is driest so that no water .ofcondensation will be carried to the garment.

4` With these and other objects in view my inventionk consistsin the following features of construction and operation which will become clear as the specification proceeds.

In the drawing- Fig. .1 is a side elevation partly in section ofa complete garment steaming v`and pressf o .ing machine;

' Fig. 2 is a fragmentary horizontal view showing the treadles by means of which the steam controlling valves for the stationary buck are controlled. i

In the above mentioned drawing I have M3 vshown but one embodiment of the invention which is now thought to be preferable, but it will be understood that changes and modiications may be made within the scopeof G the present claims without departing from the spirit of the invention.

Referring more in detail tothe figures of the drawing, I provide a base 10 having formed thereon a stationary or lower buck "7215 11. The upperportion of this buck forms a closed heating chamber 12 suitably provided with baffles 13, several of which are shown, these baffles 13 being disposed within the chamber 12 so that steam admitted to 7750 the chamber 12 will ybe distributed to all parts thereof before being exhausted through the drain conduit.

` During operation of the machine the chamber 12 is constantly supplied with steam from a boiler (not shown) usually positioned closely adjacent the steaming and pressingmachine. Preferably the upper part of the boiler is directlyconnected to the steam inlet pipe 15 and the lower part of the boiler is directly connected to thereturn or drain pipe 16 of the chamber 12. The drainpipe 16 is directly associated with the lower end of the conduit 14.- A closed lcirculatory systemv for maintaining the heating chamber at a high temperature is provided by these means. yA lcheck valve 17 is inserted in the return pipe 16 to verse flow of the steam. Y

Above this chamber in the buck '11 is a prevent resteaming chamber 18 covered by va curved i plate 19 having al plurality of apertures therethrough and suitably lmaintained in spaced position from the upper wall of the steam chamber by a number of projections` or lugs '20- formed on the upper surface of the heating chamber 12.l Over this plate 19.,k

areplaced felt or cloth covers 21 upon which thel garment is stretched during the steaming and pressing operations.

Adapted to cooperate with the stationary buck 11 is a movable presser head 22 pivotally mounted relative to the base 10 so that it may be raisedv or lowered relative to the buck 11 by means of a handle 23. Thishead 22 is provided with steam admitting means of the usual type through branch 24 of the steam supply pipe 15, and also is provided with a valve 25 mounted in the head. This valve 25 is operatedby a lever 26 to admit steam to a suitable steaming chamber (not shown)` within Vthe movable head`22. As

this upper or movable presser head 22 forms no part of the present invention it is not thought that further description will be necessary. n

The steam admitted to the chamber 12 within the lower buck 11 traverses the chamber `12 and any water of condensation formed' in the chamber may be .drained from the ,Chamber through the relatively large drain tube 14 and thence past check valve 17 to the return or drain pipe 16 leading to the lower portion of the boiler.

The draining tube 14 as shown in Fig. 1 surrounds a pipe v27 presently to be more fully described. A T shaped fitting 28 has a lateral opening through which water of condensation passes into the return pipe 16 and is returned to the boiler as above described. Inserted in the lower opening of the fitting 28 is a valve 29 having its inlet connected to a steam discharge pipe 27 extending through the drain tube 14 to a point near the top of the heating chamber 12.

lverticallyV extending pipe 31 extends to a position above the steam dome or heating ch amber 12 and below the apertured plate 19. F rom the plate 19 the steam spreads out over the pads 21 on the stationary head 11 and comes directly into contact with the garment being pressed.

Extending laterally from the ejector body 32 is a horizontal exhaust pipe 33 leading to any convenient point away from the machine and having a quick acting exhaust valve 34 mounted therein. Normally this valve 34 is maintained closed. In closed position and when the first valve 29 is open, hot and dry steam from the upper part of the heating chamber 12 passes through the pipe 27 within the drain tube 14 past the valve 29 through the ejector nozzle and thence up the vertical pipe 31. Steam, therefore, is available l vto suitably moistenand sterilize the garment being pressed.

The completion of the steaming and pressing operation with quick and eiiicient operation requires that the steam applied to the described. With the two valves 29 and 34 open, steam is forced through the ejector nozzle 30 and directly through the horizontal Vpipe 33 past the valve 34 which is wide open.

This movement of steam through the nozzle 30 forms a suction. within the suction pipe 31 driving all steam, moisture and air in the pressing members 21 of the garment pressing machine and in the garment itself outwardly fromA the machine thus promptly and eiiiciently drying the garment.

As the steam supplied to the ejector 32 is taken from a point considerably raised from the bottom wall of the dome 12, the steam admittedto the ejector 32 and to the steam chamber 18 is substantially free from water of condensation. Whatever wat-er of condensation forms in the heating chamber 12 is promptly and continuously drained through the drain tube 14 and is returned to the boiler in the usual manner. The use of the nozzle 30 therefore does not exhaust 75 and, therefore, waste any heated water from the chamber 12 and is promtly and efficiently operated by the relatively dry steam under the pressure available within the steam dome formed by the heating chamber 12.

In order to operate the valves 29 and 34, two treadles 35 and 36 are provided. As it is frequently desirable to open the steam admitting valve 29 separately from the drain valve and when the drain valve 34 is closed, a sep- CL 85 arate treadle 36 is provided for operating this valve 29. This treadle 36 is attached t0 the valve 29 by a rod 41, a spring 42 normally forcing the valve 29 toward the closed position. Normally the quick acting valve 34 in C90 the exhaust drain 33 is maintainedY in its closed position by a weight 37 acting on the free end of a pivoted lever 38 to which the valve operating rod 39 is attached.- This pivotal lever 38 is rigidly mounted upon and F95 is actuated by a transverse shaft 40, the opposite side of which has the treadle 35 adapted to be operated by the operator at any time. F or convenience the treadle 36 is pivoted freely upon the outer end of the shaft-40. 1 100 The valve 34 is never required to be opened except when the steam admitting valve 29 is open. I therefore provide means for simultaneously operating these valves 29 and 34 by depressing one treadle, namely, treadleV105 35. For that purpose the pivotal lever 38 extends forwardly and is closely adjacent at its forward end to the foot lever or treadle 36 for the steam admitting valve 29.V Therefore Whenever the shaft 40 is oscillated by "110 the treadle 35 at the right hand side of the machine, the valve 34 is opened, and also the steam admitting valve 29 is opened. With the valve 29 opened and the valve 34 closed dry steam from the heating chamber 12 passes 'f 115 through the short conduits 27 and 31 to the steaming chamber 18V and thence to the `garment being pressed. With both valves 29 and 34 opened the steam flowing through 'the ejector nozzle 30 produces a suction in the '120 steaming chamber 18 so that steam and moisture in the garment and steaming chamber 18 are withdrawn, thus quickly and thoroughly drying the garment. By operating the treadles 35 and 36 the admission of steam to 125 the chamber 18 and its withdrawal therefrom are easily controlled by the operator. I claimt 1.
